Yes, it sounds odd, but nevertheless, it is the correct usage now (IEEE 
1541). The "classic" G (GB) in computer parlance has changed to Gi (GiB, 
to diferentiate from the G prefix as used in all the rest of units in the 
SI.

The byte remains the same. The change is in the prefixes. "Gi" is read 
"gibi", meaning 2³⁰. "G" means 10⁹. This way there is no ambiguity.
